Title: The effect of shot peening on the fatigue strength of steel sheets
Author: M. SLEDZ, F. STACHOWICZ, W. ZIELECKI
Abstract: In this study, the effect of shot peening on the fatigue strength of 1.8159, 1.4301 and 30HGSA steel sheets, which are used for a screen sieve plate, was investigated. During exploitation of the separating screener, some parts of the screen sieve plate situated near the fixed edge undergo the largest deformation caused by impact bending and need special treatment. One of the methods to enhance the fatigue strength of a material is shot peening. Experimental studies showed that this method visibly increased the fatigue strength limit, especially in the case of 30HGSA steel sheet.
